Section 1: Towing and Siting
Only tow the remote power trailer with a vehicle with a minimum 3000+ lb towing capacity.
When arriving at the site, be sure to select a relatively level location, and orient the driver’s side of the trailer toward
South. The ground should be firm, but the included blocking will provide extra stability.
Figure 2: Typical towing vehicle
1. Place a block under the tongue jack, and rotate the jack into position.
2. Unclip the wiring, towing chains and tongue clip; disconnect the trailer hitch.
3. Jack the trailer up clear of the towing vehicle and pull the vehicle forward.
4. Place blocks under the rear corner jacks and engage the jacks to stabilize the trailer.
5. Locate the side jacks and extend the driver’s side jack until it reaches the last hole. The passenger side jack is not
extended. Block both jacks and crank them down until they are holding some of the trailers weight.
6. Use a level to adjust the trailer until it is relatively flat.
Section 2: Trailer Assembly
Items have been secured with Bungee cords, Ratchet straps, cardboard pieces and blocking. When unstrapping, be sure
to save all packing materials for future transport.
1. Disconnect all bungee cords.
2. Remove and retain Shipping Bracket at base of Panel Frame and the blocking from the floor (if a Windcube is
shipped inside the trailer).
3. Remove Panel Frame from trailer.
NOTE: Install Panel Frame on trailer before unpacking solar panel.
4. Mount Panel frame to trailer
a. Hold in position and install two pivot bolts at the top of the PV frame to the side of the trailer.

b. Swing out and install struts; choose an angle based on season or location (50°, 33°or 28°).
5. Tighten all bolts hand tight with wrench.
6. Mount PV panels
a. Remove ratchet straps.
b. Remove Shipping Bracket from top of stacked PV panels.
NOTE: Remove PV panels one at a time, and use a bungee cord to
support them against the wall.
c. Lift the first PV panel into position.
NOTE: The PV panels should be installed vertically with the cables and connectors on the top side. There
are two posts (as seen on the right) underneath the lower side that allow the panel to sit on the bottom
crossbar.
d. Line up bolt holes and install bolts.

e. Repeat d. and f. for remaining panels.
7. Connect each PV panel’s male and female connectors to the trailer’s male and female connectors.
NOTE: Male connectors attach to female connectors.
Section 3: Windcube Placement
1. Install the Windcube platform.
a. Remove nut and washer from pedestal support.
b. Loosen storage bolts on either side of stowed platform.
c. Lower platform into position and replace washer and nut on the pedestal support; hand tighten.
2. Install Windcube on platform.
a. Install the Windcube on the platform so it is facing North.
b. Attach the Windcube antenna to one of the two Antenna Mounts and push the end of the antenna
cable through the strain relief on the front of the trailer into the inside of the trailer. It may be
necessary to pull out the rubber gasket in the strain relief, slip it over the cable and then reinsert it

to get the cable through. Connect it to the modem inside the electrical cabinet. See Section 5
modem details.
c. Install an Ethernet cable through the strain relief in the front and connect it between the Windcube
and the Ethernet switch in the electrical cabinet.
d. Connect the DC Power Supply Cable that comes with the Windcube to the power cable on the front
of the trailer. Connect to other end to the Windcube.
e. Put the Windcube wiper pump into the provided 5 gallon bucket and feed the wiring through the
hole in the lid. Fill the bucket with distilled or deionized water and it hang under the Windcube
platform. Plug the power cable into the Windcube connection cabinet and the pump hose into the
Windcube’s wiper arm.
f. Once fully commissioned install the metal siding around the three exposed sides of the platform.
i. Fit the front side on first. The bottom of the panel sits in front of the lip of the platform.
ii. Secure the front side by installing lower front bolts hand tight
iii. Thread bolts out thru main frame upper hole, so side panels can be hung on these, and the
bolts facing out on the front panel angles.
iv. Then hang northern side on upper bolts and secure with wing nuts. Install remainder of
bolts in lower holes. Hand tighten.
v. Install the south side last because it allows access to the Windcube’s connection cabinet.
Hang side panel. Use wing nuts on upper bolts and thread in remaining bolts in lower holes.
vi. When all bolts are installed go around and tighten them all.

Section 4: Anchoring
The trailer ships with four small screw-in earth anchors that can be used if additional stability is desired. There are two
anchor points on either side of the trailer:
1. Attach one end of the anchor cable to the anchor points on the sides of the trailer.
2. Unscrew the turn buckle until it is extended as far as it can go.
3. Pull the anchor cables out to the sides at about a 45° angle.
4. Take note of where the end of the cable comes to on the ground. Come in some and
screw the anchors straight down into the ground using a metal bar.
5. Attach the anchor cable to the end of the anchor and pull excess cable thru wire rope
clips and tighten clips back up.
6. Adjust final tension with turnbuckles.
7. Repeat at the remaining three anchor points and then tighten them all down to be the
same tension.
Section 5: Connect Windcube, modem and power monitor
Typically, the Windcube’s modem should be moved to the trailer control box to share communications with the PV
power monitor.
1. Remove the modem from the Windcube
a. Open the back door (opposite connection panel).
b. Remove the modem Ethernet, antenna and power connections (3/8” wrench for antenna).
c. Remove the modem (if not already installed in the trailer).
d. Close the back door and open the front door.
e. Locate P2 on the bottom rack (4th from right, see picture below).
f. Disconnect the WHITE cable from P2 –pull the collar straight back.
g. Connect the BLACK cable to P2 –line up the red dots and push the collar straight in.

3. Turn Windcube on, connect to Laptop port and configure per Windcube the user manual.
Section 7: Transport
The solar panel frame can be secured vertically by removing the struts and letting the frame hang on the top pivot point.
The frame can then be locked into place by inserting the long locking arm into the low part of the frame. This will allow
the trailer to be moved short distances without disassembling the PV array.
Figure 3: PV Frame Locking Arm
For longer distance trips the panels should be removed and stowed in the trailer.
